Description

FIELD OF THE INVENTION

The present invention pertains to the liquid crystal display manufacturing field. In particular, the present invention relates to a flick sensor assembly.

BACKGROUND OF THE INVENTION

In the process of manufacturing liquid crystal panel, the glass substrate for manufacturing liquid crystal panel will pass through one or more liquid chambers in the wet process, in the liquid chamber strong acid or alkali solution is filled. The moving information of the glass substrate passing through the liquid chamber in the wet process is detected and informed to the next process by a flick sensor, namely when the glass substrate passes through the liquid chamber, the glass substrate contacts and pushes the vibrating component of the flick sensor, such that the vibrating component of the flick sensor is tilted to an angle, and when the glass substrate is apart from the vibrating component of the flick sensor, the vibrating component of the flick sensor return to the home position and a signal is transmitted to the next process such that the next process is prepared to take over the glass substrate. However, the flick sensor works in liquid environment, if the vibrating component of the flick sensor is not active for a long period, then the liquid will be dried, such that the vibrating component of the flick sensor is adhered and/or the restoring force of the vibrating component drops. In such cases, when the glass substrate pass through the liquid chamber, the vibrating component of the flick sensor cannot be bent and return to the home position, and the signal will not be transmitted to the next process. When the next process cannot receive the signal, the glass substrate will be soaked in strong acid or alkali solution, causing the scrapping of the products, thus reducing the yield rate of the product. Moreover, once the flick sensor failed to transmit signals, it is necessary to turn off the equipment for maintenance; the equipment utilization rate is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the flick sensor assembly 10 in the present embodiment comprises a bracket 102, a vibrating component 104, a control unit 300 and a liquid injecting device 200. The vibrating component 104 is pivotally mounted on the bracket 102. The liquid injecting device 200 is configured to inject liquid onto the vibrating component 104. As shown in FIG. 3, the bracket 102 comprises a pin 106, the vibrating component 104 is connected with the pin 106 in such a manner that the vibrating component 104 can rotate around the pin 106.

In the present embodiment, the liquid injecting device 200 is a water injecting device. And the liquid injecting device 200 comprises a liquid storage tank 210, a liquid pipeline 220 and a control valve 230, the control valve 230 is arranged on the liquid pipeline 220. Preferably, the control valve 230 is an electromagnetic control valve. The control unit 300 is electrically connected with the control valve 230.

Preferably, the control unit 300 comprises a touch panel. On the touch panel of the control unit 300, there is provided with a soft button 302 for opening or closing the control valve 230. When it is necessary to inject liquid onto the vibrating component 104, the control valve 230 can be opened by clicking on the soft button 302. When it is not necessary to inject liquid onto the vibrating component 104, the control valve 230 can be closed by clicking on the soft button 302 once again. By this way, the remote control of the control valve 230 can be realized.

The liquid pipeline 220 is made of perfluoroalkoxy alkane.The inner diameter of the liquid pipeline 220 is 4 mm˜10 mm. The inner diameter of the liquid pipeline 220 is preferably 5 mm. The liquid pipeline 220 made of perfluoroalkoxy alkane is resistant to strong acid and strong alkali solution. And the liquid pipeline 220 can be secured to make sure that the outlet of the liquid pipeline 220 faces the vibrating component 104. In the present embodiment, the outlet of the liquid pipeline 220 is mounted on the bracket 102. As shown in FIG. 3, the distance D between the outlet of the liquid pipeline 220 and the vibrating component 104 is 10 mm˜60 mm. When the distance D between the outlet of the liquid pipeline 220 and the vibrating component 104 is 10 mm˜60 mm, the liquid from the outlet of the liquid pipeline 220 can reach the vibrating component 104.

Based on experiments, when the distance D between the outlet of the liquid pipeline 220 and the vibrating component 104 is about 30 mm, the liquid can push the vibrating component 104 to move and return to the home position quickly.
